Abstract (en)
[origin: EP1691413A1] The method involves providing a P doped material inclusion (18) that destroys or damages an electronic component e.g. microcontroller, in case of a thinning attempt of a silicon wafer of the component by a rear side (17) of a silicon substrate (15). The inclusion acts on the polarization of the wafer. The silicon wafer is polarized by the rear side. The wafer is tested with a polarization of the substrate. An independent claim is also included for a chip card comprising an electronic component.
